Description

Battery electrode casting and melting device

This creation is a battery electrode casting and melting device, which involves battery production and processing technology, and aims to automatically draw the metal hot melt in the furnace, and then cast and melt the battery electrodes to maintain better conductivity.

As shown in the first and second figures, a general storage battery includes a plurality of battery pole groups 100, a accommodating box 200, and an upper cover 300 enclosed above the accommodating box 200. In the accommodating box 200, partitions are arranged at intervals. The compartments are divided into a plurality of accommodating spaces, and each accommodating space contains a set of battery pole groups 100 and acid solution, and the acid solution and the battery pole group 100 produce chemical reactions to achieve the effect of electric energy conversion.

An electric bridge 101 is arranged above each battery pole group 100. In the plural battery pole groups 100, in addition to the electric bridge 101, the positive and negative electrode bridges 101 are integrated into a diode 102 to pass through the two battery pole groups 100. Out of the upper cover 300. When the two poles are respectively electrically connected to the external terminals 103 and connected to an external power source, the storage battery can charge and discharge the multiple battery pole group 100 through the two terminals 103, the two poles 102, the bridge 101 and other electrodes.

In the figure, the battery has a variety of specifications for different types of products, and the structure is slightly different, such as the arrangement direction of the plural battery pole groups, the shape of the bridge and the pole, and the location of the pole. The manufacturing process is roughly Including the steps of plate arrangement, ear root cutting, bridge casting, punching into the groove, acid injection, etc. However, there are some differences in the manufacturing process for batteries of different specifications. For example, some batteries use the battery pole group into the container. After placing the box (that is, the punching into the slot in the step), the two adjacent bridges are electrically joined by crimping or welding; some batteries are electrically welded between the two adjacent bridges when the bridge is cast, and then the The plural pole groups are placed in the containing box.

The advantage of joining the bridge, or the terminal and the pole by crimping or welding, is that when the battery pole group is still in a separated state, it is easy to put into the containing groove, and it is not easy to collide with the separator and damage the pole group. Terminals and poles are often joined by welding, such as TWM550911, TWM368570 and other known technologies.

However, the crimping bridge uses a crimping device to heat and squeeze the two bridges, so that the two bridges are deformed and joined by force. However, because of this, the two bridges are prone to uneven force and different crimping areas. One condition affects the conductive effect.

In addition, when welding the electric bridge, or the terminal and the pole, it is welded by a soldering iron tip with hot melt. However, after soldering, there will be residual metal beads on the surface of the soldering iron tip, which will affect the quality of the next soldering. Oxides are easily formed on the surface of the soldering iron tip, which makes it difficult for the soldering iron tip to get hot melt, which will also affect the conductive effect and the automated manufacturing process.

In terms of conductive effect, the conductive effect of casting welding is better than that of crimping or welding. For example, the creator has created TWM556185, TWM536987, TWM468024 and other technologies. As shown in the third figure, casting welding mainly uses a jig or fixture 400 to clamp all the battery pole groups 100 and turn them upside down. The root of the ear is immersed in the mold 500 (commonly known as the casting mold) containing the hot-melt lead liquid. After the hot-melt lead liquid is cooled and solidified, the casted pole group and electric bridge are taken out and turned over, and then the groove is inserted.

The above-mentioned integrated electric bridge after casting and welding has better conductive effect, but because it needs to be clamped in the process, and then the whole group of poles is turned over, and then the ear root is immersed in the mold containing the hot melt lead liquid, so the drive The equipment is more complicated, and it takes a long time to wait for the hot melt lead liquid to cool the solid mold. In addition, the pole groups that have completed the bridge casting and connection must be placed in the containing space of the containing box with the partition. Internally, it is relatively inconvenient in operation, resulting in low production capacity and high cost.

In view of this, the creator has accumulated many years of research and practical experience in related fields, and specially created a battery electrode casting and melting device to improve the complicated process of casting and welding battery terminals, poles, bridges and other electrodes. .

The purpose of this creation is to provide a battery electrode casting and melting device, so that the battery can use an automated device to draw the hot melt in the furnace to join the battery electrodes, such as terminals and poles, or two adjacent Between the bridges, maintain better conductivity.

In order to achieve the above purpose, this creation is a battery electrode casting and melting device, which can weld the electrodes of a battery to be processed. The device includes a melting furnace containing a metal hot melt, a hollow reclaiming tube, and a plug. among them: The reclaiming tube can move relative to the melting furnace. The bottom end of the reclaiming tube has an opening and can be submerged in the hot melt to allow the hot melt to flow into the reclaiming tube from the opening; the plug can be relatively The material pipe moves up and down to a closed position or away from the closed position; and When the reclaiming tube is immersed in hot melt, the plug should be able to move to the closed position so that the hot melt is sealed in the reclaiming pipe. When the reclaiming tube or the electrode of the battery to be processed moves to a welding Position, after the take-out tube is positioned above the electrode of the battery to be processed, the plug is displaced away from the closed position to release hot melt, and the electrode of the battery to be processed is cast and melted from top to bottom.

With the above structure, this creation does not need to invert the battery pole group and then immerse it in the mold when welding the bridge and the bridge or the pole and the terminal of the battery pole group, nor does it need to wait for it to cool and solidify. Turn over and move to the next process, which can greatly save man-hours and effectively increase productivity; especially in this creation, whether the electrode group is first placed in the battery accommodating slot and then the battery electrode is cast, or the battery electrode is cast first Melting, and then placing the pole group into the accommodating groove, can be applied, breaking through the long-term insurmountable problem of battery electrode welding.

The following further describes the implementation of each element:

Compared with the prior art, this creation successfully overcomes the major deficiencies of the known technology that the battery must be turned upside down to melt the electrode. It combines the advantages of battery electrode casting with excellent conductivity and easy processing, which can save a lot of money. Working hours and equipment cost effectively increase production capacity, which is extremely industrially usable.

The following is based on the technical means of this creation, enumerating the implementation methods suitable for this creation, and the description with the drawings is as follows:

As shown in the fourth and fifth figures, this creation is a battery electrode casting and melting device, which is mainly used for the welding process of the electrode of the battery to be processed. The electrode includes the casting and melting between the electric bridge and the electric bridge, or the pole The welding between the casting and the terminal, the electrode after welding has excellent conductivity, which can effectively improve the manufacturing quality of the battery, and the welding process can greatly save man-hours and equipment costs, and effectively increase the production capacity.

As shown in the figure, the device includes a melting furnace 10 containing a metal hot melt, a hollow take-out tube 20, and a plug 30, wherein the take-out tube 20 is arranged in a group that can drive the take-out tube 20 and the sealing The bottom of the mechanical arm 40 where the plug 30 is displaced includes a heating platform 41 disposed above the reclaiming pipe 20. In implementation, the hot melt is tin liquid, lead liquid or other composite metal melt suitable for welding the electrodes of the battery.

The mechanical arm 40 is mainly used to drive the reclaiming pipe 20 to move relative to the furnace 10 so that the reclaiming pipe 20 can be submerged in the hot melt from top to bottom. During implementation, it is not ruled out that the reclaiming pipe 20 is a fixed position. After the furnace 10 is moved below the reclaiming pipe 20, it is moved upward so that the reclaiming pipe 20 is submerged in the hot melt.

As shown in the fifth figure, the bottom end of the hollow reclaiming pipe 20 has an opening 21, above the opening 21 is provided a moving space 22 for the displacement of the plug 30, and above the moving space 22 is provided a storage space 23. The opening 21, moving The space 22 and the storage space 23 are in communication with each other, and a limit portion 24 is protruded along the inner wall at the junction of the moving space 22 and the storage space 23.

The sealing plug 30 is located in the moving space 22, and its outer diameter is larger than the limiting portion 24, so that the sealing plug 30 can move up and down in the moving space 22, and when it moves downwards, it can pass through the opening 21 , Move upwards until it abuts against the limiting portion 24.

As shown in the figure, a driving rod 31 is provided above the plug 30. The driving rod 31 is coaxially pierced in the center position of the reclaiming tube 20, and can drive the plug 30 to move upward to a closed position (the eighth figure) and to Move down away from the closed position (Figure 10). In addition, the surrounding wall surface of the plug 30 is provided with at least one longitudinal guide groove 32.

As shown in Figures 6 and 7, when the reclaiming tube 20 and/or the melting furnace 10 move relatively, so that the reclaiming tube 20 is immersed in the hot melt in the melting furnace 10, the driving rod 31 can drive the plug 30 downward Move out to the bottom of the opening 21 to allow the hot melt to flow from the opening 21 into the reclaiming pipe; of course, it is not a necessary condition for the plug 30 to move down to the bottom of the opening 21, as long as the hot melt can flow from the opening 21 to the reclaiming pipe The storage space 23 in the tube 20 is sufficient.

In addition, there are two protruding blades 33 at the bottom of the plug 30 in the figure. The driving rod 31 can drive the plug 30 and the blades 33 to rotate. The purpose is to stir the hot melt and allow the hot melt to flow. The speed of entering the opening 21 and the storage space 23 is increased.

As shown in the eighth and ninth figures, when the reclaiming tube 20 is submerged in hot melt, and the hot melt flows into the storage space 23 in the reclaiming tube 20 from the opening 21, it is driven by the drive rod 31 After the plug 30 moves to the aforementioned closed position, that is, moves upward to abut against the limiting portion 24, the hot melt is sealed in the storage space 23 of the reclaiming tube 20; at this time, the aforementioned mechanical The arm can move the entire reclaiming pipe 20 to move the reclaiming pipe 20 out of the furnace 10.

Similarly, the movement of the reclaiming pipe 20 is not a necessary condition, and it is also a feasible implementation to drive the furnace 10 relatively far away from the reclaiming pipe 20. In addition, after the take-out tube 20 is moved out of the furnace 10, in order to maintain the liquid phase of the hot melt, the heating platform 41 shown in the fourth figure can heat the take-out tube 20 to avoid cooling of the hot melt, thereby speeding up the extraction. The speed at which the material tube 20 takes the material. In practice, the reclaiming tube 20 has been heated by immersing it in the hot melt. As long as the immersion time is sufficient to allow the reclaiming tube 20 to rise above the melting point, the heating platform 41 is not necessary equipment.

As shown in the tenth figure, after the hot melt is sealed in the storage space 23 by the take-out tube 20, the take-out tube 20 can be moved to the welding position above the electrode 601 of the battery 600 to be processed by a mechanical arm. After the plug 30 is far away from the above-mentioned closed position, the storage space 23 and the opening 21 can be restored to the connected state, and the hot melt in the storage space 23 can automatically drip onto the electrode 601 of the battery through the opening 21, and then from the top Then, the electrode 601 of the battery 600 to be processed is cast and melted.

As shown in the fifth and tenth figures, in this embodiment, the longitudinal guide grooves 32 provided on the surrounding wall of the plug 30 can guide the hot melt to accurately drop to the welding position, and when the plug 30 is located In the closed position (the eighth and ninth figures), the upper part of the longitudinal guiding groove 32 and the limiting portion 24 are in an isolated state to prevent the hot melt from leaking downward in the closed state. Furthermore, the aforementioned two blades 33 can not only rotate and stir the hot melt tin liquid, but also allow the hot melt liquid to flow and remove the oxides of the welded body as quickly as possible, thereby accelerating the welding.

With the above structure, this creation does not need to invert the battery pole group and then immerse it in the mold when welding the bridge and the bridge or the pole and the terminal of the battery pole group, nor does it need to be cooled and solidified. Turning over and moving to the next process can greatly save man-hours and effectively increase productivity; especially for the casting and melting device of this creation, whether the electrode group is first placed in the battery accommodating slot and then the battery electrode is cast and melted, or first It is applicable to casting and melting the electrodes of the battery, and then placing the electrode group into the holding tank, which breaks through the long-term insurmountable problem of battery electrode welding and has significant progress.

The above-mentioned way of moving the plug 30 to the closed position is to move up to abut against the limiting portion 24, and the hot melt is sealed in the storage space 23 of the reclaiming pipe 20; during implementation, it can also be used The hot melt is sealed under atmospheric pressure. DETAILED DESCRIPTION As shown in the eleventh to fifteenth figures, the opening 21 is also located below the storage space 23. Above the storage space 23 is provided at least one vent 25 communicating with the outside atmosphere, and the plug 30 is movable The ground is located above the vent 25.

When the take-out tube 20 is immersed in the hot melt in the furnace 10, the plug 30 is far away from the vent 25, so that the upper part of the storage space 23 is in communication with the atmosphere, and the hot melt can directly enter the storage space 23 from the opening 21 At this time, the plug 30 is driven to move to the closed position to close the vent 25, and the reclaiming tube 20 is moved away from the furnace, because the hot melt in the storage space 23 is only subjected to atmospheric pressure at the bottom opening, so The hot melt can be sealed in the storage space 23.

When the reclaiming pipe 20 is moved to the welding position above the electrode 601 of the battery 600 to be processed, the plug 30 is moved away from the closed position, so that the upper and lower storage spaces 23 communicate with the atmosphere through the vent 25 and the opening 21 respectively , The hot melt can be automatically released due to gravity to process the electrode 601 of the battery 600.

This embodiment is particularly suitable for welding processes that require only a small amount of hot melt. For example, in the fifteenth figure, the electrode 601 of the battery 600 is composed of poles and terminals, and a small amount of hot melt can weld the terminals on On the pole.
